  • Effect of moisture in coal on station heat rate and fuel

    Aug 04, 2016· 3.2 Effect of coal movement and handling. While internal moisture affects the coal combustion process, external (mechanical) moisture gives rise to difficulties in handling (transfer and flow ability) of coal with severe capacity reduction of all equipment in the coal plant ranging from crushers to conveyors. External moisture also creates combustion difficulties by creating thermal lag

  • Coal Analysis and Production Information Thermo Fisher

    Elemental coal analyzers provide coal analysis (sulfur, ash, moisture, and calorific value) in order to spot coal quality trends, track silo content, provide estimates of the coal quality about to enter a coal-fired boiler, and alert the plant to potential derate situations or potential emissions excursions.
